Title: Improvements in voltage regulator for direct current motor with drive current control
IPC: H02P7/34
Filed: 1970-02-24
Abstract: 1284032 Automatic current control GENERAL ELECTRIC CO 24 Feb 1970 3 March 1969 8804/70 Heading G3R A network 61 compensates for the resonant characteristic introduced by a current feedback loop of a voltage regulator for a D. C. motor 45, whereby step function signals applied to the regulator result in smooth voltage changes during speed transitions. A summing junction 35 receives the resultant of a positive reference signal 13, negative voltage rate feedback signal 15, and positive signal 17 which is responsive to the counter EMF compensated for IR drop, through the network 61. The modified signal is summed with a current feedback signal 37, and the signal so produced is applied through amplifier 39 to thyristor circuit 41 associated with the field winding of generator 43 which supplies the armature of the motor. The signal 15 is derived from the motor terminals through a capacitor. Under steady state conditions, capacitors 21, 31, 25, simulate open circuit connections whereby operational amplifier 23 saturates and applies maximum voltage to junction 35. Under transient input voltage conditions, the capacitors 21, 31, shortcircuit the amplifier 23 and no voltage is applied to junction 35. Resistors 19, 27, 29 in combination with capacitor 25 divert some voltage, thereby modifying the output of the amplifier 23 within the aforesaid extremes.

Title: Improvements in and relating to metal cutting tools
IPC: B23D13/00
Filed: 1947-04-01
Abstract: 655,251. Planing ; gear-cutting. NATIONAL BROACH & MACHINE CO. April 1, 1947, No. 8859. Convention date, July 15, 1946. [Class 83 (iii)] A metal-cutting tool, particularly a gear cutter of the reciprocating pinion type, comprises a rigid central portion 64, a rigid outer portion 65 carrying cutting teeth 66 and a flexible web 67 interconnecting the central and outer portions. The teeth have cutting edges at both ends and in either direction of the cutting stroke the cutter flexes when the teeth engage the work to provide clearance behind the cutting edge within the limits imposed by abutment surfaces 70 on rigid members 68. The flexing of the cutter provides some clearance on the sides as well as the tips of the teeth since the sides do not lie in radial planes, but additional clearance just behind the cutting edges of both portions may be provided by hollow grinding them. When cutting helical gear teeth, Fig. 4, the flexing of the cutter results in the cutter teeth 80 operating on one side 82a of the gear slot during the for ward stroke and on the other side 82c during the return stroke. Cutting of a shoulder gear is effected on the down stroke only, the cutter returning to its intermediate position when the lower cutting edge clears the work, so providing clearance for the return stroke. A machine employing the cutter is described, in which a motor 13, Fig. 1, drives gearing rotating the cutter rod 19 and the work spindle 50 in unison and also reciprocates the cutter rod along straight or helical splines 39 in the gear 31 by means of a crank disc 16 connected to a crosshead 18. It is stated that the invention may be applied to ordinary planing.
